Copy Hero is a Chrome extension designed to simplify the process of converting newline-separated lists into JSON arrays or SQL-style VALUES. This tool is particularly useful for developers and data analysts who frequently work with lists of data, enabling them to quickly transform and copy formatted data for use in scripts or SQL statements.

Users can operate Copy Hero in two ways: by manually pasting the list into the input field or by using a keyboard shortcut that reads from the clipboard. Once the shortcut is activated, users need to grant permission for clipboard access, allowing for a seamless conversion experience. This functionality enhances productivity by streamlining data handling tasks directly within the browser.
